Abstract
A lifeline system includes a lifeline and a hub around which the lifeline is coiled. The hub deforms to absorb energy at a predetermined level of force exerted thereon by the lifeline. For example, the hub can be deformable to absorb energy so that a peak fall arrest force in a drop test of the lifeline system with a 220 pound mass attached to the lifeline over a distance of up to 6.56 feet is not more than 1900 pounds. In several embodiments, the peak fall arrest force is no more than 1500 pounds or no more than 1349 pounds.
